2 StructurePRO LVL Design Manual 1-800-700-4788

Our CompanyOur total focus on the engineered wood productsbusiness is what distinguishes us. At EasternEngineered Wood Products we take pride in provid-ing our customers with premium quality productsand industry-leading services. Our StructurePROLVL™ is manufactured to provide consistent, high performance floor and roof systems.

About LVL Providing the superior performance and durability ofengineered wood, StructurePRO LVL is perfectlysuited to spans bearing heavy loads and multi-spanapplications. The normal problems associated withwide lumber sizes – like decreased dimensional sta-bility and uniformity – do not apply to our LVL,which utilizes ultrasonically tested and gradedDouglas Fir veneer.

Engineered for QualityChecking is minimized because StructurePRO LVL iscured in a controlled process in which waterproofadhesives boost stability and reduce warps andtwists. All products are machine-ripped to generate uniform size and rigid, flat surfaces withinherently superior nail-holding characteristics.

We are confident that our products will provide ourcustomers with consistent high performance whenhandled and installed in accordance with our installation guide.

Tested for strength and engineered for quality,StructurePRO LVL represents our ongoing commit-ment to unsurpassed performance and service.

StructurePRO LVL is third-party tested by APA-TheEngineered Wood Association, a leading qualityassurance organization.

General notes for this product guide:1. All tables assume dry conditions. Calculations

are based on NDS and IBC and ICC-ESR#2913.2. Lateral support of the compression edge of all

beams must be provided at 24" on center.3. Application tables include live load reductions

applied in accordance with 2006 IBC.4. Tables apply to Dead, Floor Live, Roof Live and

Snow loads. Lateral loads must be considered by the building designer.

5. This design manual is intended to be used for preliminary design purposes; a complete structural analysis should be preformed by a design professional.

6. Beams that are 13/4" x 16" and deeper require multiple plies.

Bearing Length

Notes:1. Use any combination of 13/4" and 31/2" members using proper nailing or bolting guidelines.2. Minimum bearing length is 11/2". Bearing across the full width of the beam is required.3. Reported bearing length is based on 750 psi compression perpendicular to grain stress of the LVL member.Beams bearing on #2 and better, 2x plates must be increased by the following factor:

Allowable Uniform Loads (plf) - 2.0E - Floor 100% - 13/4" Width

Notes:1. Single 13/4"members are limited to 14" in depth. For multiple member applications, multiply the allowable uniform load by the corresponding number of plies in the built-up beam.2. Table displays the maximum uniform load which may be applied to the member in addition to it's own weight.3. Total load deflection is limited to L/240.4. Assumes the more restrictive of simple or continuous (2 span) condition.5. Spans are measured from the center to center of bearing.6. Depths of 16" and greater should be used with a minimum of two plies unless designed specifically as a single ply of 13/4"with proper lateral bracing spaced at 24" along the length of the beam. (Example: the marriage beam for each half of a manufactured home before units are joined.)

7. Table indicates LVL beams continuously laterally braced at the top edge by subfloor (for joist application) or at maximum 24" o.c. by framing fastened directly to the LVL or to single or double top plate nailed to the LVL.

8. Table is based on 13/4" width. Values may be multiplied by 2 for 31/2" width, 3 for 51/4", and 4 for 7".

Detail A Detail B Detail C Detail D

Notes:1. Design values based on 2005 NDS and PR-L283 APA and ICC-ES ESR-2913 Product Report.

2. Dry conditions of use.3. Design values may be increased for load duration; see 2005 NDS.4. Verify load capacity of framing member in addition to connection design.

5. Use minimum two rows of fasteners for up to 117/8" LVL beam depth and minimum three rows of fasteners for 14" to 24" LVL beam depths.

StructurePRO® LVL Handling Instructions and Sizing Software

Handling and Storage Guidelines• LVL should be protected from the weather and stored lying flat.

• Product must not be stored in contact with the ground.

• Store LVL in wrapped bundles, provide air circulation and support bundleswith 2x4 stickers.

• Protect from the weather on the job site both before and after installation.LVL is intended for use in covered, dry conditions only.

• Except as described in this product guide, LVL should not be cut, drilled ornotched.

• Do not install wet or visually damaged product.

Clear SealerAll StructurePRO LVL is fully sealed with a factory applied industry-leading premium grade sealer. The sealerrepels water absorption and improves durability during typical distribution yard and jobsite storage conditions.Once a factory sealed LVL product is cut, a coat of water repellent sealer should be applied to the freshly cutend to prevent moisture from entering the cut end.

Sizing SoftwareTo better assist engineers, designers and specifiers, Eastern Engineered Wood Products has partnered withKeymark of Boulder Colorado, an industry leader in design software to provide KeyBeam®. This single membersizing program recognizes all the United States building codes and offers printable design calculations andbeam capabilities. The software user can specify simple span applications, point loads, cantilevers and manymore common applications. Please contact Eastern Engineered Wood Products Sales to learn more aboutreceiving a complimentary copy of KeyBeam Software.
